Abstract
A process for the production of a compound of general formula <CHEM> , wherein R represents cyano, carboxy which may be esterified or amidated or tetrazolyl which may be substituted, comprising brominating the corresponding methyl compound with a brominating agent such as N-bromoacetamide, N-bromophtalimide, N-bromosuccinimide and so on in a halogenated hydrocarbon solvent in the presence of an azobis compound.
